To subtract the given fractions:
9 7/10 - 6 1/4
First, convert the mixed numbers to improper fractions:
9 7/10 = (9 * 10 + 7)/10 = 97/10
6 1/4 = (6 * 4 + 1)/4 = 25/4
Next, find a common denominator, which in this case is 20:
97/10 = (97*2)/20 = 194/20
25/4 = (25*5)/20 = 125/20
Now, subtract the fractions:
194/20 - 125/20 = (194 - 125)/20 = 69/20
The difference is 69/20, so the answer is:
